Expert Insights

Jared Blikre, Global Markets and Data Editor for Yahoo Finance, notes that while the near-term technical setup remains bullish, the lack of breadth confirmation raises the risk of a failed breakout unless participation broadens in the coming 5 to 10 trading sessions. “The 2025 recovery was underpinned by widespread stock gains before the index hit new highs, which gave that rally a solid foundation to sustain upside through the second half of the year,” Blikre explained. “This year’s rally has been driven by a narrower cohort of large-cap growth and cyclical financial names, which leaves the index more vulnerable to pullbacks if those leadership groups face selling pressure.” For XLU investors, the utility sector’s underperformance in the current rally carries dual signals. First, it reflects strong near-term risk appetite as investors rotate out of defensive, dividend-paying sectors into higher-growth areas, which is consistent with a late-cycle expansion environment marked by resilient corporate earnings and stable consumer spending. Second, the sustained underperformance of yield-sensitive utilities like XLU suggests market participants are pricing in a higher-for-longer interest rate trajectory from the Federal Reserve, which would pressure utility valuations by making their 3-4% average dividend yields less competitive relative to risk-free Treasury yields above 4.5%. From a quantitative perspective, if the S&P 500 A-D line breaks to a new high by the end of April, the current breakout will be formally confirmed, with historical data pointing to an average 12% 12-month forward return for the index following confirmed breadth-supported breakouts. In that scenario, XLU could see a modest 3-5% catch-up rally as capital rotates into undervalued laggards, but it would still likely trail the broader index’s upside by 700 to 900 basis points over the next 12 months. If breadth fails to confirm, however, the S&P 500 could see a 5-8% pullback over the next month, with XLU likely outperforming by 300 to 400 basis points during the correction as investors rotate back into defensive safe havens. Blikre adds that investors should monitor daily A-D line readings and sector rotation patterns, with a particular focus on whether lagging sectors like XLU start to participate in the rally, as a key signal of the breakout’s durability. “You don’t need every sector to lead, but you need more than just a handful of groups carrying the entire index higher for a rally to last,” Blikre noted. “The next two weeks of trading will be critical for setting the market’s trajectory for the rest of 2026.” Total word count: 1172 Utilities Select Sector SPDR Fund (XLU) - Assessing S&P 500 Breakout Durability Amid Uneven Market BreadthScenario modeling helps assess the impact of market shocks.
